## Abstract

The present investigation is part of a program aimed at examining the mathematical basis of reaction rate theory (Bartholomay,*Bull. Math. Biophys.* **20**, 1958) from the point of view of individual molecular events. Certain inconsistencies resulting from the classical procedure of using stoichiometric “chemical equations” to represent the kinds of mechanisms involved are pointed out and remedies are suggested by the introduction of set-theoretic notation within the framework of a so-called*Molecular Set Theory*. It is concluded that whereas ordinary algebra is a suitable basis for stoichiometry, in discussing mechanisms of chemical reactions,*molecular set theory* is more appropriate. This is a theory of material transformations which is patterned after*abstract set theory*: the individual molecules of a chemical species and chemical transformations from one species to another correspond to the abstract concepts of elements or points of a set and their mappings into other sets respectively. The new notions of*exact molecular sequences* and*equivalence classes* of molecules arising from this study of chemical reactions may be of purely mathematical interest when referred back to the context of abstract set theory.
